Abstract
We propose the Robust Overlay Architecture for Mobility (ROAM) to
provide seamless mobility for Internet hosts. ROAM is built on top of
the Internet Indirection Infrastructure ( ). With , instead of
explicitly sending a packet to a destination, each packet is
associated with an identifier. This identifier defines an indirection point in , and is used by the receiver to obtain the
packet.
ROAM
takes advantage of end-host ability to control the
placement of indirection points in to provide efficient
routing, fast handoff, and preserve location privacy for mobile
hosts. In addition, ROAM allows end hosts to move simultaneously, and
is as robust as the underlying IP network to node failure. We have
developed a user-level prototype system on Linux that provides
transparent mobility without modifying applications or the TCP/IP
protocol stack.
Simulation results show that ROAM's latency can be as low as 0.25-40%
of Mobile IP. Experimental results show that with soft handoff the TCP
throughput decreases only by 6% when there are as many as 0.25
handoffs per second.
